Stalemate over an agreement between Britain and the European Union on post-Brexit trade rules for Northern Ireland has been blocking the formation of a new executive, which runs the British province's devolved power-sharing administration, since elections there in May.

"The UK and Irish Governments reaffirmed their commitment to doing everything possible to facilitate the re-establishment of the executive by 28 October and the full functioning of all of the political institutions established by the Belfast/Good Friday Agreement," said the communiqué, published by the British government.

The conference between senior British and Irish ministers in London is not directly linked to the Brexit trade negotiations, which have resumed separately this week with some positive signs that a deal might be reached.

The communique made only a passing reference to those negotiations, which are principally held between Britain and the EU Commission.

"The conference noted the ongoing discussions to address issues around the Northern Ireland Protocol and to find an agreed way forward," the communique said.
